Abstract

Bei einer axialdurchströmten Gasturbine, im wesentlichen bestehend aus einer mehrstufigen Turbine (1), welche einen auf einer gemeinsamen Welle (13) angeordneten Verdichter (10) antreibt, bei welcher der zwischen der Turbine (1) und dem Verdichter (10) liegende Wellenteil eine Trommel (14) ist, die von einer Trommelabdeckung (15) unter Bildung eines Ringkanals (20) umgeben ist, wobei im Ringkanal (20) eine gegen die Trommelabdeckung (15) dichtende Labyrinthdichtung (21) angeordnet ist, und die Trommelabdeckung (15) zusammen mit der Stirnseite (18) des Turbinenrotors (3) einen radial verlaufenden Radseitenraum (19) begrenzt, bei der seperate Leitungen (22) zur Führung der Turbinenrotorkühlluft vom Verdichter (10) zur Stirnseite (18) des Turbinenrotors (3) angeordnet sind und die Verbindung zwischen diesen Leitungen (22) und dem Radseitenraum (19) jeweils über mindestens eine Dralldüse (23) erfolgt, bei der Kühleinrichtungen (24) für den Turbinenrotor (3) und seine Laufschaufelkränze vorhanden sind und die gesamte rotorseitige Kühlluft für die Turbine (1) dem Verdichter (10) im Bereich des Verdichteraustritts entnommen wird, ist im Bereich des Trommellabyrinths (21) mindestens eine Absaugvorrichtung (25) für die Leckageluft und einen Teil der Kühlluft angeordnet. Die Absaugvorrichtung (25) steht mit den Kühleinrichtungen der hinteren Turbinenstufen in Verbindung.

Figure 00000001
In the case of an axially flow-through gas turbine, consisting essentially of a multi-stage turbine (1) which drives a compressor (10) arranged on a common shaft (13), in which the shaft part lying between the turbine (1) and the compressor (10) has one Drum (14) which is surrounded by a drum cover (15) to form an annular channel (20), a labyrinth seal (21) sealing against the drum cover (15) being arranged in the annular channel (20), and the drum cover (15) together with the end face (18) of the turbine rotor (3) delimits a radially running wheel side space (19), in which separate lines (22) for guiding the turbine rotor cooling air from the compressor (10) to the end face (18) of the turbine rotor (3) are arranged and the connection between these lines (22) and the wheel side space (19) takes place in each case via at least one swirl nozzle (23), in the case of the cooling devices (24) for the turbine rotor (3) and its rotor blades nze are present and the entire rotor-side cooling air is taken from the turbine (1) of the compressor (10) in the region of the compressor outlet, of the drum labyrinth is arranged (21) at least one suction device (25) for the leakage air and a portion of the cooling air in the region. The suction device (25) is connected to the cooling devices of the rear turbine stages.
